Artemis, Genome viewer demo: This demo loads a genome for viewing. In this
demo a local copy of genome is loaded, however Artemis can also load sequences from the
Internet.

ClustalX, Sequence alignment demo: This demo calls clustalx with a filename as argument. The filename is PPIases, which contains sequence of 10 proteins in FASTA format. To perform sequence alignment from top menu select: Alignment -> Do Complete Alignment. On the pop-up box click on ALIGN.

PyMOL, Structure visualization and high-quality image rendering demo: This demo loads a sample project with a protein and 3 conformations of a peptide in the active-site. To change the display use options from S (show), H (hide), L (label) and color menu. To render a high-quality image use ray option in the main menu. To save image use from main menu: File -> Save Image.

Rasmol, Structure visualization demo: This demo loads a protein for visualization. You can use mouse to rotate the molecule. Display and colors can be changed from top menu.

Raster3D, High quality image rendering (for biomolecules) demo: This demo
creates a high quality image of a protein active-site.

TINKER, Molecular modeling demo: This demo creates a TINKER file from PDB
file for a protein, performs a single point energy calculation and computes molecular
volume and surface area.
